Certain novel synchronized quasi-resonant topologies for achieving soft-switching DC/DC boost and flyback converters with minimum voltage stress across the switches
Abstract:This paper presents some novel synchronized quasi-resonant circuits for achieving soft-switching DC/DC boost and flyback converters. These topologies use coupled inductors with capacitor for resonating circuit to achieve zero voltage switching of the converters. The circuits have minimum voltage stress across the switches. Moreover, they have reduced commutation losses and increased switching frequency. The paper explains the principle of operation of the circuit and describes the analysis of each mode of oper… Show more
